WATER-CLOSET VALVE.

SPECIFICATION forming part of Letters Patent N0. 429,422, dated June 3, 1890.

Application filed August 10, 1889. Serial No. 320,433. (No model.)

To all whom it may concern.-

Be it known that I, NATHANIEL A. GoNK- LIN, a citizen of the United States, residing in the city of Brooklyn, county of Kings, State of New York, have invented a new and useful Water-Closet Faucet, of which the following is a specification.

My invention relates to that class of waterclosets wherein measures are provided to detach from the general flow a quantity of wator for once flushing the hopper, and has no application to hoppers taking water direct from the main supply.

The objects of my improvements are, first, to combine in one faucet, in a simple manner, all the functions of the complicated apparatus commonly used for the purpose; second, to provide for the forcible discharge into the hopper Without undue noise, and, third, to avoid freezing.

In the accompanying drawings, Figure 1 is a vertical section of the faucet-shell, showing valves in place; Fig. 2, an elevation; Figs. 3,

4, and 5, horizontal cross-sections through the lines X X and Y Y. Fig. 5 shows a modification of the waste-drip NV. I

As shown in Fig. 1, the flow of Water through the pipe A is stopped by the Winged valve I. Beyond this the recess H, thereservoir H H, the passage U, and the discharge-pipe V are all in communication and are free of Water. If now force be applied to raise the valvestem T, the piston-valve O first closes the pas sage U and then lifts the valve I, allowing water from the pipe A to flow into the recess H, which remains in constant communication with the air-tight reservoir H H, of any convenient form or size, but preferably of from seven hundred to one thousand cubic inches capacity, and having but the one opening H. This flow ceases when the pressure in the reservoir H H becomes equal to that in the pipe A, the air being compressed above the water in the reservoir. Upon releasing the stem T the pressure upon the valve 0 forces it from the passage U and releases the valve I, which the street-pressure then seats. The reservoir H H is now discharged by the expansion of its compressed air through the pipe V at a gradually reducing pressure. The drip-outlet or waste at W then drains the Water remaining in the pipes into the soilpipe, to which it should be connected at a point below the faucet, allowing the air to again enter at V. At the inner end of the drip WV a valve WVW is set that will close under high pressure, but is loaded to open by its own weight when the pressure falls below, preferably, two pounds per square inch. If the faucet be placed below the frost-line and thus drained, the water-closet hopper may be placed in situations exposed to freezing temperature without injury.

Instead of the valve WV WV, a drip-pipe W, as shown in Fig. 5, may project into the pipe V, with its mouth turned in the direction of the current, thus preventing a forcible backflow to the waste IV until the main fiow becomes moderate, when the pipes will be drained, as before.

It is evident that when the faucet is so placed that the final outlet into the hopper is no higher than V complete drainage may be secured through that channel, when no drip will be required.

I claim as my invention, for which I desire to secure Letters Patent of the United States- 1. In a water-closet faucet having a cylindrical discharge-passage, an accurately-fitted cylindrical plug guided to entirely leave the passage during a fraction of its total movement, and when in this position separated or having its stem separated by'a similar fraction of its total movement from a closed inlet-valve opening in the opposite direction, in combination with said inlet-valve, substantially as described, and for the purpose set forth.

2. In a Water-closet faucet having a cylindrical discharge-passage, an accurately-fitted cylindrical plug guided to entirely leave the passage during a fraction of its total movement, and when in this position separated or having its stem separated by a similar fraction of its total movement from a closed inlet-valve opening in the opposite direction, in

combination with said inlet-valve and a reservoir lying in part between said valves, submovement, and when in this position separated or having its stem separated by a similar fraction olf its total movement from a closed inlet-valve opening in the opposite direction, in combination with said inlet-valve, a reservoir lying in part between said valves, a drlp-ontlet, and the automatic drip-valve V arranged substantially as and for the purpose set forth.
